不同作物土壤水浸提液对远志的化感效应
Allelopathic Effects of Soil Water Extracts from Different Crops on Polygala tenuifolia
摘要
Abstract
[Objective]To establish a reasonable farming system and find suitable rotation crops for Polygala tenuifolia.[Method]This study selected eight common crops to study the effects of soil water extracts of different crops on seed germination and seedling growth of Polygala tenuifolia.[Result]The soil water extracts of different crops had inhibitory effects on the germination of Polygala tenuifolia seeds.The higher the concentration of the extract,the stronger the inhibitory effect.The average total inhibition rate from small to large was soybean,millet,corn,wheat,sorghum,castor,oil sunflower and sesame.The soil water extracts of different crops had a promoting effect on the growth of Polygala tenuifolia seedlings.The growth of seedlings and roots was gradually inhibited as the concentration increased compared to other treatments.The overall growth of seedlings and roots of Polygala tenuifolia in each treatment showed a negative correlation;castor,sesame treatment,Polygala tenuifolia had tall seedlings and short roots;soybeans,corn and millet treatment,Polygala tenuifolia had long roots,low seedlings and poor growth.The root length and root weight of soybean,corn,wheat,sorghum and millet treatments were higher than those of CK.The POD activity of Polygala tenuifolia seedlings,except for sesame and castor,increased with the increase of concentration.The overall MDA content showed an in-creasing trend with the increase of concentration,while the SOD activity first increased and then decreased with the increase of extract concen-tration.[Conclusion]Based on the comprehensive growth index and physiological index,soybean,corn,wheat and millet are more suitable rota-tion crops for Polygala tenuifolia.关键词
